He plans to arrive in Boulder Saturday, and begin classes Monday.
"I'm pretty excited," he said.
Katoa did not play organized football until his junior year at Cottonwood. But he quickly picked up the game, and became a force on the field. His high school coach, Cecil Thomas, said Katoa is a humble kid, despite all the attention he received over the past year as his recruiting skyrocketed.
On the field, Thomas described Katoa as a player who "goes hard every play. In practice, we get his very best effort. He's a leader by example. He gets other kids to step up their game. When things go south, he's a guy who can keep everybody under control."
A 5-star player, Katoa is the No. 2-ranked middle linebacker prospect by Scout.com. He committed to Colorado in early December.
Last weekend, Katoa played in the all-star game in Texas.
"It went really well," Katoa said. "It was a little taste of what's on the next level. There were some big guys who could move. There were some great players over there and I know I'll see some of them in the future."
He said getting to Colorado for the spring semester will help him with the adjustment to college life.
"It will help me out with school and getting used to the environment," he said. "I'll just try and fit in with the whole program and how the schedule works."
Katoa also noted he's looking forward to the offseason weight training program that's in store for him.
